Objective To observe the influence of long-term treatment with inhaled corticosteroid on biochemical bone indexes and bone mineral density (BMD) in children with asthma. Methods The design was a randomized, paralleled group study with 3 low dose regiments of 100, 200,300 micrograms of budesonide per day in 45 children with asthma aged 5-8 years old for 12 months. Before inhaled corticosteroid therapy and 6th,12th month,clinical effects were observed and lung function(FEV1) was measured; concentration of serum osteocalcin(OST),insulin-like growth factor-1(IGF-1),bony alkaline phosphatase (BALP) and urinary deoxypyridinolin: creatinine (DPD/Cr) were measured; BMD was examined by dual energy X-ray absorptiometry. Results Clinical evaluation was improved and there was significant increase in FEV1 of asthmatic children. The amount of serum OST was slightly higher,yet no significant compared with that of normal control group. There was significant increase of serum BALP in asthmatic children after treatment; there was significant increase in serum IGF-1 of patients group after treatment compared with in normal children at the same age group; there was significant decrease in urinary DPD/Cr after treatment.There was no significant decrease in BMD before and after treatment at the hip (neck of femur , trochanter of femur ,Ward′s triangle),the lumber area of the spine (L2-4) and forearm (ultradis, distal). Conclusion Long-term treatment with low does corticosteroid dose not restrictedly affect bone metabolism and BMD in children with asthma.

Clinical evidence of hematopoietic restoration with umbilical cord blood (UCB) grafts indicates the UCB can be a useful source of hematopoietic stem cells for routine bone marrow reconstitution. Considering (10 +/- 5) x 10(8) nucleared cells per cord blood unit, there is a potential limitation for the use of cord blood in adults, which, however, can be overcome by ex vivo expansion of cells. A prerequisite for expansion is the significantly higher recovery of MNC, CD34+ cells and colony-forming cells (CFC) by thawing cryopreserved MNC. Cooling rate always acts as a critical factor that can affect the recovery of cells. Although the rate of - 1 degrees C/min is adopted in most of the cryopreservations, no data has been reported about the detailed effects of different cooling rates. The aim of the study was to reveal the different effects of cooling rates on cryopreservation of hematopoietic stem cells from cord blood. UCB samples were collected, and cryopreserved as mononuclear cells (MNC) with different cooling rates of - 0.5 degrees C/min, - 1 degrees C/min, - 5 degrees C/min, and the recovery and viability of MNC and CD34+ cells, the clonogenic capacity and the ex vivo expansion potential of UCB progenitor cells were evaluated after thawing. With - 1 degrees C/min cooling rate, the recovery of MNC reached 93.3% +/- 1.8% , viability 95.0% +/- 3.9% , recovery of CD34+ cells 80.0% +/- 17.9% , and clonogenic recovery were 87.1% +/- 5.5%, 88.5% +/- 8.9%, 86.2% +/- 7.4% for BFU-E CFU-GM CFU-MK, respectively. After 14 days of liquid culture, no significant difference was detected in CFC expansion between fresh and cryopreserved MNC cells with - 1 degrees C/min cooling rate, but this was not the case with - 0.5 degreesC/min and - 5 degrees C/min. In conclusion, it was demonstrated that controlling the rate at - 1 degrees C/min is more suitable for cryopreservation of hematopoietic stem cells than - 0.5 degrees C/min and - 5 degrees C/min.

OBJECTIVE To explore the mechanisms of the volatiles of Wendan granule for the treatment of senile dementia,network pharmacology method integrating absorption,distribution,metab-olism, and excretion (ADME) screening, target fishing, network constructing, pathway analyzing, and correlated diseases prediction was applied. METHODS Twelve small molecular compounds of WDG were selected as the objects from 74 volatiles with the relative abundances above 2%,and their ADME parameters were collected from Traditional Chinese Medicine Systems Pharmacology platform (TCMSP), and then the corresponding targets, genes, pathways and diseases were predicted according to the data provided by TCMSP,DrugBank,Uniport and the Database for Annotation,Visualization and Integrated Discovery(DAVID).The related pathways and correlation analysis were explored by the Kyoto Encyclo-pedia and Genomes (KEGG) database. Finally, the networks of compound-target, target-pathway and pathway-disease of WDG were constructed by Cytoscape software. RESULTS Twelve compounds interacted with 49 targets, of which top three targets were Gamma-aminobutyric acid receptor subunit alpha-1 (GABRA1), Prostaglandin G/H synthase 2 (PGHS-2) and Sodium-dependent noradrenaline transporter.Interestingly,these targets were highly associated with depression,insomnia and Alzheimer′s disease that mainly corresponded to mental and emotional illnesses. CONCLUSION The integrated network pharmacology method provides precise probe to illuminate the molecular mechanisms of volatiles of WDG for relieving senile dementia related syndromes,which will also facilitate the application of traditional Chinese medicine in modern medicine,as well as follow-up studies such as upgrading the quality stan-dard of clinical medicine and novel drug development.

Objective To explore the role of microRNA-155 ( miR-155 )/suppressor of cytokine signaling 1 ( SOCS1 ) pathway combined with IL-17 in modulating the early progression of Schistosoma japonicum.Methods BALB/c mice were infected subcutaneously with cercariae of S.japonicum before being sacrificed at 8 and 14 weeks after infection to collect liver samples for pathological observation by H&E staining .The spleens of mice were collected to calculate the spleen index.The level of IL-17 in serum was determined using ELISA.Furthermore, qRT-PCR was used to detect the expression of miR-155 and SOCS1 mRNA in the spleens of mice .Results Compared with normal group , the spleen index in the model group was increased significantly along with the loss of relative body mass .H&E staining revealed that the deposition of parasite eggs began to appear in the liver tissue at week 8 post-infection.Meanwhile, there were a large number of inflammatory cells infiltrating to form the eosinophilic granuloma.Over time, the formation of egg granulomas and the infiltration of inflammatory cells were alleviated on week 14 post-infection.The level of IL-17 in serum and the expression of miR-155 in the spleen were peaked on week 8 post-infection, and decreased sharply on week 14, but were still evidently higher than those in normal group .The expression of SOCS1 mRNA was progressively increased both on week 8 and 14. Conclusion The data indicates that miR-155 might cooperate with IL-17 to modulate SOCS1 in the development of S.japonicum infection.

Objective To explore the effects of artesunate on the proliferation,cell cycle,apoptosis and apoptosis-related protein of bortezomib-resistant multiple myeloma (MM) cells.Methods Human MM cell line NCI-H929 was treated with bortezomib in a dose-dependent manner to establish a bortezomib-resistant cell line NCI-H929BR.The logarithmic growth phase NCI-H929BR cells were divided into control group(blank culture medium)and two concentration experimental groups (artesunate,25,50 μg · mL-1)and treated for 48 h.The inhibitory role of artesunate on NCI-H929BR proliferation was measured by MTT assay.Cell apoptosis and cell cycle were determined by flow cytometry.The Bcl-2 family proteins (Bcl-2,Bcl-Xl,Bax) were detected by Western blot.Results Bortezomib resistance index of NCI-H929BR is 20.12 times than NCI -H929.After administration artesunate for 48 h,the proliferation rate of NCI-H929BR in the low and high concentration experimental groups were 62.46％,33.48％;there was significant difference compared with control group (all P＜0.05).The artesunate dramatically decreases NCI-H929BR proliferation in a dose-dependent manner (P ＜ 0.05).After treatment for 48 h with artesunate,the proportion of G1 phase cell cycle in high concentration experimental group was increased compared with control group [(51.63 ± 4.02) ％ vs (34.72 ± 2.43) ％,P ＜ 0.05].The proportion of apoptosis cell was increased,early apoptosis in high concentration experimental group and control group were (13.10 ± 1.53)％,(2.32 ± 1.02)％;and late apoptosis in the two groups were (10.26 ±2.42)％,(1.93 ± 0.69) ％;comparison between two groups,the difference had significantly (all P ＜ 0.05).In addition,artesunate significant decreased of Bcl-2 and Bcl-Xl protein expression and increased of Bax protein expression in a dose -dependent manner.Conclusion Artesunate could inhibit NCI-H929BR proliferation,increase apoptosis,cause G0/G1-arrest and down-regulate Bcl-2 and Bcl-Xl expression,while up-regulate Bax expression.

OBJECTIVETo evaluate the feasibility and curative effect of thymectomy for myasthenia gravis (MG) by video-assisted thoracoscopic surgery (VATS) through right anterior-lateral approach.

METHODSFifty-six patients of MG were treated with thoracoscopic thymectomy and mediastinal fat dissection through right anterior-lateral approach from August 2001 to October 2007. The feasibility, safety, complication and remission for MG were retrospectively analyzed.

RESULTSFifty-five operations were completed by VATS. The mean operative time and blood loss were (96.2 +/- 52.1) min and (68.7 +/- 21.4) ml, respectively. The brachiocephalic vein injury by the electric coagulator occurred in two cases and one of them performed thoracotomy for homeostasis, the other performed ligation. The postoperative pathology showed hyperplasia in 38 cases, atrophy in 5 cases, thymoma in 12 cases and cyst of thymus in 1 case. And the operative complication included one myasthenia crisis (1.8%) at the third day and one death (1.8%) at the eighth day because of postoperative hemorrhage. The average length of stay was (7.9 +/- 2.9) d. All cases were followed up from one to seventy months. Eight (14.3%) of complete remission, 39 cases (69.6%) of partial remission and 7 cases (12.5%) of no change were found. The total effective rate was 83.9%.

CONCLUSIONSThoracoscopic thymectomy through right anterior lateral approach is technically feasible, safe and minimally invasive. It has a high remission rate for MG.
